Tenancy & Legal Insights for 21 Days of Occupancy

Mid-Month Apportionment Guidelines

For a tenancy spanning 21 days, both the move-in day and the move-out day are counted as full billable tenancy days under US statutory standards. Ensure your written lease agreement specifies whether calculations use the actual calendar days or the standard 30-day banking convention.

Step-by-Step Calculation Example for 21 Days:

Assuming a monthly rent of $1,800.00 in a 30-day month:

  1. Divide monthly rent by total days: $1,800 ÷ 30 = $60.00 per day
  2. Multiply daily rate by occupied days: $60.00 × 21 = $1,260.00

Total Prorated Rent: $1,260.00
